I'm finially been bit by the idea of putting together a preheresy army. I looked around an one i've notice doesnt get alot of attention is the Alpha Legion, most likely because thiers not alot of information about them. For the purposes of fluff, I am considering using Kosarro Khan, unmounted as the HQ choise. THis gives the whole army the outflank ability plus a few other things. Shrike was my first choise, but didint feel fluffy enough for a very secretive army, that uses a lot of misdirection. The core of the amry will be made up of scouts and a few tact squads. any other ideas to keep it in fluff, but still have a chance to do well?
